Cheaper, larger and better infrared detectors grown on silicon wafers could give more scientists access to infrared astronomy and further spur the hunt for exoplanets and the study of the universe’s ...

Polarization, as a primary physical quantity of light, is of great interest to almost all optical sciences and technologies. Along with linear polarization detection, circular polarization (or light ...

(Nanowerk News) What do motion detectors, self-driving cars, chemical analyzers and satellites have in common? They all contain detectors for infrared (IR) light. At their core and besides readout ...

Much like some snakes use infrared to 'see' at night, researchers are working to create similar viper vision to improve the sensitivity of night-vision cameras. Much like some snakes use infrared to ...

A dust sensor is an optical electronic system to detect fine particles such as dust. In principle, an optical dust sensor detects the dust particle concentration the in air by using an optical sensing ...

The telescope 'time machine' will deliver 13.5 billion years of cosmic history. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The newest deep ...

Detecting light beyond the visible red range of our eyes is hard to do, because infrared light carries so little energy compared to ambient heat at room temperature. This obscures infrared light ...
